In this paper we obtain the following extension of [1]} for weakly porous sets,
given in terms of the Muckenhoupt exponent \(\operatorname{{Mu}}(E)\)  that
we introduce in Definition REF . For a porous set \(E\subset {\mathbb {R}}^n\)  it holds that
\(\operatorname{{Mu}}(E)=n-\operatorname{dim_A}(E)\) , see Section  for details.
